Moderator: How would this work with an open-ended question? We have asked for house numbers for addresses in the UK. They are usually only 4 numbers, however, with letters and characters can be longer. If they are over 4 characters long, we want to be able to ask them if they are sure. Is this possible?

Hi Amy
It would take custom scripting to accomplish this task. I don’t know about your time or budget constraints, but unless this question is absolutely vital to your survey then I believe that developing this type of script would quickly put you over the point of diminishing returns.
Sometimes you just have to trust your respondents and hope for the best. I would like to think that most people can enter their home addresses correctly.

You would not be able to do this within the question itself. You can validate a response so that it is accepted or rejected according to specific formatting requirements, but you can’t evaluate the response itself.

If the question is a radio-button type question, you could use logic to setup a followup question that would appear immediately when the respondent selects the triggering option.

If the question is a checkbox-type question, you can also use logic to setup a followup question, but it would have to appear on the following page (answers to checkbox questions are not evaluated until the respondent hots the NEXT button).
